Abstract

L'invention concerne un appareil de réseau qui peut fournir divers services logiciels, notamment à la fois des services de plate-forme, tels des services de méthode d'accès, et un service d'équilibrage de charge. Un réseau peut comprendre un appareil de réseau qui, à la fois, fournit un ou plusieurs services de plate-forme et agit en tant qu'équilibreur de charge. Lorsque deux appareils de ce type ou plus sont utilisés ensemble, ils peuvent remplacer une partie importante d'un réseau conventionnel. Ainsi par exemple, lorsqu'un appareil de réseau reçoit une communication client, son service d'équilibrage de charge peut déterminer si l'un de ses propres services de plate-forme traitera la communication ou si la communication sera transmise pour traitement à un autre appareil de réseau. De plus, si le service d'équilibrage de charge d'un appareil de réseau est défaillant, un autre appareil de réseau peut assurer l'équilibrage de charge. De manière similaire, si un autre service d'un appareil de réseau est défaillant, l'appareil de réseau peut continuer à assurer l'équilibrage de charge mais transmettre pour traitement à un autre appareil de réseau les communications requérant le service défaillant.
